While lying on your back, straighten one leg up in the air. Hold the back of your thigh with your hands and feel a stretch in your hamstring muscles, in the back of your upper thigh.(Trish McAlaster/The Globe and Mail)

After holding the stretch for 10 to 30 seconds, rotate your ankle so that your foot moves clockwise in the air. Do 10 circles, then 10 more counter-clockwise. Switch and repeat on the opposite leg.(Trish McAlaster/The Globe and Mail)
